responsive slideshow-size in Twenty-Twelve ?

Hey guys,

is it somehow possible use a slideshow in the Twenty-Twelve theme which automatically adjusts to the Monitor-Size / Screen resolution ?

I need a slideshow for my photographies which is big enough on a big screen but fits to the screen, when viewed on a laptop monitor as well.

The slideshow should be part of the post, not like the lightbox player.

any help would be greatly appreciated!!

P.S.

if i didn’t express myself well enough, you can check out this (non-wordpress) website, and you’ll know what i’m looking for: https://www.alexandergronsky.com/
